Emil D, Kattennsnn, Dover, N. 1., acdgncr to Swiss Knitting Company,

Dover, N. 1., a cerinvention relates to a connection between two non-overlapping or abutting edges of textile materlal.

More particularly stated, the invention relates to a connection between an edge of a textile fabric having parallel elastic threads, the edge being substantially parallel to said parallel threads or a textile fabric having a warp or having a selvage edge or an edge in which the threads are locked so they will not slip, and an edge of a band, welt 0r cuff formed of knitted, woven or braided fab- At the present time many garments, such as girdles, wrsets, bathing suits, or bifurcated garments are made of elastic material having parallel elastic threads. Such garments in order to be satisfactory must fit snugly and be stable, or

so-heldin place that they will not slip, roll or be otherwise displaced. In order to accomplish such a fit or such stability the garments are provided with elastic cufls, bands or welts which are often formed with a diiferent texture or weave from that of the main body of the garment. Being formed of different texture the cuffs must be connected in some manner to the edge of the body of the garment. In certain instances the edges have been sewed together, but this forms an objectionable double thickness of material and the seam does not have sufficient elasticity to permit the necessary elongation.

This invention has for its salient object to provide a connection between and a method 01'' securing or uniting cuffs, welts or bands of elastic textile material to an edge of a fabric having parallel elastic threads or a selvage or locked edge so constructed that the connection will be simple and will connect the edges without. forming a thick edge or double thickness of material.

Another object of the invention is to provide an elastic textile fabric with a marginal band or cuif so joined at their edges as to securely connect the edges in non-overlapping relation without forming a thickened edge portion, and furthermore so joined as to permit the connection to stretch beyond the limit of elongation of the fabric without breaking. 7

Another object of the invention is to form a connection between two pieces of elastic material, one of which has a warp so arranged as to provide a connection that will stretch with the materials or fabrics connected and will permit the materials joined to be stretched to their full limit of elasticity.

Further objects of the invention will appear from the following specification taken in connection with the drawing which forms a part of this application, and in which Fig. 1 is a perspective view somewhat diagrammatic, illustrating the connection between the textile fabric having a warp and the edge of a knitted, woven or braided fabric;

Fig. 2 is a plan view on an enlarged scale illustrating the connection between the two fabrics;

Fig. 3 is a sectional elevation taken substantially on line 3-3 of Fig. 2;

Fig. 4 is a view similar to Fig. 3 but showing the loops which connect the edges pulled tight;

Fig. 5 is an elevation view of a garment, such as a girdle, having ends or bands connected thereto in accordance with the invention;

Fig. 6 is a perspective view of a portion of a looping machine on which the edges of the fabrlcs are placed to be joined or connected by the Fig. I is a perspective view of the edges connected by the loops; and

Fig. 8 is an elevation showing the arrangement of the loops, which join the fabric edges.

The invention briefly described consists of a connection between and a method of joining the edges of two pieces of fabric, one piece offabric having an elastic warp or parallel elastic threads and the other piece being formed of knitted, woven or braided material. The invention has been particularly worked out with elastic textile fabrics and consists of connecting the edges of the two fabrics by looping, the loop stitches preferably extending around one or more elastic warp threads or around one or more parallel elastic threads of the fabric. the fabric is a selvage or locked edge the loops may extend around one warp or elastic thread.

Further details of the invention will appear from the following description.

Fig, 1 illustrates diagrammatically a body piece A of textile fabric having a warp, and this piece may be formed of woven or netted material. The direction of the warp threads is indicated by the arrow.

At 8 there is shown a piece of textile material formed of knitted, woven or braided fabric. The edges of the pieces A and B are joined by double loops C and D which are formed by a looper in the usual well known manner.

Fig. 2 illustrates more in detail an embodiment of the invention in which the piece A of material has warp threads II and weft or filler threads i i.

The piece of material designated as B is knitted and has a plurality of or a course of loops ii.

In order to join these two pieces of material manner shown in Fig. 7, doubleloopsbeing-illus trated in the drawing. It should be understood however, that a single thread looper maybe used if desired.

Fig. 4 illustrates in greatly exaggerated-form the loops C and D pulled tight to enclose a plurality of warp threads I0.

As above stated, if the material'has a selvage edgeit is not necessary to form the loops C and D'around a plurality of warp threads, although this is desirable. 5

The method and connection above described may be used wherever it is desired to form a connection between a'textile fabric having an elastic warp or parallel elastic threads and a fabric of knitted, woven or braided material, but it is particularly applicable for forming the connection between a cuff or bandof elastic material, such as that shown at I5 inFig. 5, and an edge of a body l6 of elastic fabric.

The connection may be used in many types of elastic garments, as for instance, in girdles, corsets, underwear, pajamas, 'bathingsuits, or many kinds or types of bifurcated garments to join an elastic cuff, welt or band to one or more edges thereof.

It should be understood that the illustrations in the drawing are greatly exaggerated and the joint or connection in the actual garment forms a very small and unobjectionable bead on the in- 1 outside.

side ofthe garment which is not visible from the From the foregoing specification it will be clear that asimple, practical and effective method of joiningthe edges of a textile fabric having an elastic warp or parallel elastic threads and I a band or piece of knitted, woven or braided fabric has been worked out and'that the connection formed will securely jointhe pieces of material in abutting or non-overlapping relation and in a manner to permit the full limit of stretch of the joined pieces to'be available andwithout the objectionable features encounteredwhen these parts are sewed or otherwise connected together in g overlapping relation.

In other words and briefly stated, the connection may be used to join the edges of any two pieces of elastic material where a smooth, stretch 'able connection is desired.

Although onespecificembodiment of the invention has been particularly shown and described, it will be understood that the invention is capable of modification and that changes in the construction and in the arrangement of the various cooperating parts maybe made without departing from the spirit or scope of the invention, as expressed in the following claims.

3. A fabric article formed of connected textile fabrics, comprising one fabric having elastic warp threads extending along an edge thereof and sub-, stantially parallel thereto .and another fabric having a series of loops extending along an edge thereof, said edges being connected in abutting relation by looping stitches engaging around one or more of the elastic warp threads of the first mentioned edge and through the loops of the second mentioned edge.
